*@**0:28* This part of the video stopped me from throwing away an expensive flashlight. THANK YOU!

[@DanielHodges21]

Thanks for the vid! The "tail cap switch" was the issue on mine. I tightened it according to instructions in the video and now my flashlight works....I take back all the negative remarks I said about the person that invented the LED flashlight, lol.

[@JosephHoltwick]

Thanks so much for this video. I have a nice, bright Husky LED flashlight that stopped working. I was able to determine the tail cap switch was a little loose and tightening with the use of needle nose pliers as you suggested did the trick!! I would have never figured this out. I'll have plenty of light when taking our dog out late at night.

Cleaning the contacts like you said work I have an xr9 stowed away brand new in box case today I took it out but did not turn on its a new battery pack. I was dumbfounded I followed your instructions on cleaning the contacts with alcohol and sure enough it worked thank you for that simple tip will keep that in mind I understand from olite These batteries are on backorder

I have swollen D cell batteries in my Pro-4 tactical flashlight, how do you get them out???

[@jesusbencomo3495]

Hello I love your video. I have a 3 Watt 2D digital Brinkmann flashlight which has a display and buttons for off/on, Test and battery status divided in 3 sections. Yesterday it was working but i press the test button and now doesn't work. I am afraid that the problem is in the microprocessor, because I bought it used, I wonder if letting it without batteries for some days, the capacitors will drain and the problem will be solved. Would you have any suggestions for me please?

How to install batterys

[@nandhasura6700]

i have led flash light made by hasky 1500 lumens 3 mod and having with front face side loose contact .i need to get instruction to dis assembled it .

[@eljeffe8806]

Since the fit between the flashlight body and batteries is so tight, any battery deterioration can make the batteries unmovable and they are stuck. The Front end of LED flashlights are not easy to remove, depending on the model. Is there anything we coat the battery part of the flashlight with to make it easier to remove batteries if they deteriorate? I have had to discard two $40 flashlights when the AA batteries corroded a little and they became stuck in the flash light body.

I find that 95% of the time the problem with flashlights that use three AAA batteries in a little plastic holder, is that there are 4 to 6 places where a coil spring has to make contact with a thin metal contact. One or more of the spring surfaces or contact surfaces gets corroded. They may still look shiny and new, but you may have to scour ALL of those surfaces (including the springs) with a piece of sand paper.

How to correct led module circuit if that is not working?

[@hamidrezakarimi2733]

Hello, the problem of not charging the flashlight battery happened to me. I tried with different batteries, but it does not charge again. Please help me.

[@randalnihei9764]

What if you have a Duracell led flashlight? Looks like the taillight switch is snapped into place, not screwed in.

[@mzolisimabulu8490]

My flash light is the Led Lenser P5R2. I have had for 2 years now and I like it but the switch seems to be have a problem can you assist me on how to repair the switch with the video here on You Tube. When Im charging it the light for charging does not show and this occurred after it had fallen about 1m onboard the ship.

[@stevequate1797]

Do t know why everyone posts the same old shit, my granddaughter can jump out a tail cap, mine still won’t come on, it’s in the head assy, why. Any anyone make a trouble shooting video on find the problem & fixing it. Everyone can solder in a led, how to find the problem in The head. Obviously it is harder than hell to disassemble and troubleshooting it finding the problems
